CAUTION
Discharging the Probe Between Measurements
Measuring a node having a DC voltage potential charges blocking capacitors inside of the
probe. Ground the probe tip after measuring such nodes to discharge the probe capacitors.
Failure to do this can result in damage to sensitive circuits in the DUT, especially if it is
an active device.
Grounding the Probe
Proper grounding is important when making measurements with any probe. The probe is supplied with
two grounding devices: an alligator-type ground clip and a slip-on type ground tip. Use the shortest
ground path possible. Proper grounding becomes more important as frequency increases. For optimum
measurements in a factory environment, design your circuits with ground-plane feedthroughs next to
every test point.
Retracting and Extending the Protective Sleeve
Hold the probe wand in one hand, pointing the tip away from yourself. Grasp the probe sleeve in the
other hand and turn about 1/4 turn counter-clockwise. Now, pull the sleeve toward you while slowly
turning it counter-clockwise. The sleeve will now retract quickly with little counter-clockwise rotation.
Reverse this procedure to extend the sleeve.
